Ooids (/ ˈoʊˌɔɪd /, [1] from Ancient Greek ᾠόν (ōión) 'egg stone') [2] are small (commonly ≤2 mm in diameter), spheroidal, "coated" (layered) sedimentary grains, usually composed of calcium …

Oolite or oölite (from Ancient Greek ᾠόν (ōión) 'egg stone') [1] is a sedimentary rock formed from ooids, spherical grains composed of concentric layers. [2] Strictly, oolites consist of ooids of …

2024年7月1日 · Ooids are concentrically-laminated, sedimentary grains produced through successive stages of carbonate precipitation and abrasion that typically form above wave base …

Oolite is a sedimentary rock made up of ooids (ooliths) that are cemented together. Most oolites are limestones — ooids are made of calcium carbonate (minerals aragonite or calcite). Ooids …

2019年3月1日 · Ooids are spherical or ovoidal carbonate grains (typically <2 mm in diameter) of smooth, well-laminated cortices that accrete around a nucleus, typically a bioclast, peloid, …

2018年1月29日 · Here we investigate a rare and beautiful geophysical problem that combines both of these processes; the shape evolution of carbonate particles known as ooids.
